【摘要】 综合利用钻井、测井、地震资料,运用层序地层学原理,在珠江口盆地番禺低隆起韩江组下段识别出4个层序界面,划分为3个3级层序,即SQ1、SQ2、SQ3。通过井-震划分对比,建立了工区内韩江组下段层序地层等时格架。在等时格架建立的基础上,总结出研究区发育的3种岩性地层圈闭,主要受层序界面、最大海泛面、初始海泛面控制。更多还原

【Abstract】 By comprehensively using well drilling,logging and seismic data and sequence stratigraphic principles,the lower segment of Hanjiang Formation of Panyu low uplift in Pearl-river Mouth Basin was recognized as 4 sequence boundaries and it was divided into 3 third-order sequences,including SQ1,SQ2 and SQ3.According to well-seismic division and comparison,isochronal sequence stratigraphic framework of lower segment of Hanjiang formation was established.On the basis of the isochronal sequence stratigraphic framework,three kinds of litho-stratigraphic traps were summed up in the studied area,they were mainly controlled by sequence boundary,maximum flooding surface and initial flooding surface.更多还原
